A display device including a substrate; a first electrode on the substrate; a partitioning wall on the first electrode that includes a first opening that overlaps the first electrode; a touch detection electrode on the partitioning wall; a low refractive layer on the partitioning wall and the touch detection electrode, the low refractive layer including a second opening that overlaps the first opening; and a high refractive layer on the low refractive layer. Planar shapes of the first opening and the second opening are polygons, each including a series of sides, and a distance between one side of the first opening and the second opening is different than another side of the first opening and the second opening in a plan view.

Display device

A display device includes a substrate, a pixel electrode disposed on the substrate, a bank layer which is disposed on the pixel electrode and in which a pixel opening overlapping the pixel electrode is defined, an encapsulation layer disposed on the pixel electrode and the bank layer, a sensing electrode disposed on the encapsulation layer, a first insulating layer which is disposed on the sensing electrode and in which an opening overlapping the pixel opening is defined, and a second insulating layer which is disposed on the first insulating layer and has a higher refractive index than a refractive index of the first insulating layer, where a side inclination angle of the first insulating layer in the opening of the first insulating layer is different depending on a position of the opening of the first insulating layer.

Display device and photomask for defining opening in the display device

A display device includes a substrate, a pixel electrode disposed on the substrate, a bank layer which is disposed on the pixel electrode and in which a pixel opening overlapping the pixel electrode is defined, an encapsulation layer disposed on the pixel electrode and the bank layer, a sensing electrode disposed on the encapsulation layer, a first insulating layer which is disposed on the sensing electrode and in which an opening overlapping the pixel opening is defined, and a second insulating layer disposed on the first insulating layer and having a higher refractive index than a refractive index of the first insulating layer. The opening of the first insulating layer includes a first edge and a second edge separated from an edge of the pixel opening and extending in different directions from each other and a first extension part disposed at a portion where the first edge and the second edge meet.

Display device including insulating layer defining opening

Some embodiments provide a display device including a substrate having an opening area, a peripheral area surrounding the opening area, and a display area surrounding the peripheral area, a transistor and a light emitting element on the substrate, an encapsulation layer on the light emitting element, a first touch insulating layer on the encapsulation layer, an overcoat layer on the first touch insulating layer, and defining a first opening, and a cover layer filling the first opening, wherein at least one of the overcoat layer and the cover layer extends from the display area to the peripheral area, and wherein the substrate includes a depression pattern that is filled by the overcoat layer or the cover layer.

A display device includes a first substrate and a second substrate, which face each other, and each of which includes a display area and a non-display area disposed outside the display area, a first light-blocking layer disposed in the non-display area, and a dummy color layer, in which a boundary dividing the display area and the non-display area is defined, and which is disposed in the non-display area of the first substrate to be adjacent to the boundary, where the dummy color layer includes a section in which a distribution density of the dummy color layer is decreased from the boundary to the outside of the non-display area.
